Title: Contact structure for puffer-type gas-blast circuit interrupter
IPC: H01H33/915
Filed: 1976-02-23
Abstract: The contact structure for a puffer-type compressed-gas circuit interrupter comprises a pair of elongated aligned axially separable contacts one of which is hollow and has an end portion provided with a plurality of axially extending, circumferentially spaced-apart contact fingers adapted to resiliently grip the other contact in telescoping relation therewith. The fingers are surrounded by a snugly sleeve ending short of the tips of the fingers permitting the puffer mechanism to direct a radial (cross-blast) jet of arc-extinguishing gas through the interstices between said tips exhausting subsequently through the interior of the tubular contact. The sleeve screens off the residual, major part of the length of the fingers to prevent a radial flow of gas therebetween at this level. It has been found that this arrangement provides an unexpected increase in the breaking power of the apparatus as compared to contact structures having sleeves covering the total length of the contact fingers or no sleeves at all.
Patent ES-445629-A1 (ES)
Title: Fluid pressure operated disc brake with piston expansion means to compensate for brake shoe wear
IPC: F16D65/54
Filed: 1976-02-27

Patent ES-460237-A1 (ES)
Title: Energy transfer
IPC: C07C303/44
Filed: 1977-06-29
Abstract: This invention relates to a process for neutralizing detergent acid mixes containing unreacted sulfating agent such as sulfuric acid with an alkaline component such as sodium hydroxide. The neutralization process is highly exothermic and contains as a by-product large amounts of sodium sulfate. Due to the exothermic nature of the reaction it is necessary to use heat exchangers to regulate the temperature of the reaction mass following the addition of the alkaline component. When the sodium sulfate is supersaturated in the reaction mass, it has been observed that sulfate salts buildup upon the surfaces of the heat exchanger and eventually the system must be shut down to remove the buildup. This invention is therefore directed to a continuous neutralization and heat exchange process wherein the downtime required for removal of the sulfate salts from the heat exchanger surfaces is effectively eliminated.

Title: Diamond Drill Core Bits
IPC: E21B10/48
Filed: 1978-11-17
Abstract: A diamond drill coring bit has an annular crown 6 formed from radially extending composite segments 18 spaced apart circumferentially by a circumferential spacer material 24, all integrally bonded together. Each composite segment consists of diamond impregnated segments 20 spaced radially from each other by a radial spacer material 22. The diamond impregnated segments 20 have greater abrasion resistance than the radial spacer material 22 such that the latter will wear faster than the former. The radial spacer material 22 likewise has greater abrasion resistance than that of the circumferential spacer material 24 such that the latter will wear faster but not so fast as prematurely to expose the composite segments 18. The circumferential spacer material 24 has good thermal conductivity to conduct heat from the composite segments 18, and substantial ductility to absorb drilling shocks.
Patent ES-477965-A1 (ES)
Title: High voltage switch and capacitive drive
IPC: H03K17/689
Filed: 1979-02-22
Abstract: A high voltage capacitive drive circuit for coupling a dc or pulsed dc input voltage from a control input to a relay having a high voltage output circuit is described in which the output of the high voltage relay circuit is electrically isolated from the control input thereto without the use of optical couplers. The combined capacitive drive circuit and high voltage switch circuit of the present invention may be integrated on a single silicon chip using conventional isolation fabrication techniques to provide good isolation between the control input and the output of the high voltage relay circuit. A pair of matched capacitive couplers are driven in a push-pull mode to pump electrical charge to a floating control circuit which turns on the high voltage relay contact. An exclusive OR circuit prevents high voltage signals on the contact terminals from inadvertently turning the contact ON or OFF by being responsive only to out of phase inputs. The described high voltage switch and capacitively coupled drive circuit is suitable for fabrication on a single semiconductor chip.
Patent ES-479253-A1 (ES)
Title: Method of Cooling a Reciprocating Continuous Casting Mould
IPC: B22D11/055
Filed: 1979-04-03
Abstract: In a method of cooling a reciprocating continuous casting mould for steel strands having side walls (2) with channels (3) flowed through by a cooling medium, the upper part of the side walls is less cooled than the rest, the cooling in the region of the side walls contacted by molten metal during reciprocation is retarded and thereby the maximum temperature in the mould is shifted in the upward direction by approximately the height of the reciprocating movement, and the surface temperature in the reciprocating region is kept constant. The cooling may be retarded by incorporating heaters 11, insulation spaces, or insulation materials into the mould wall. Defects in the strands are reduced.
